METHOD OF LABELING CONTAINERS.

Specification of Letters Patent.

Patented June 22, 1920.

Application filed November 5, 1918. Serial No. 261,225.

To all whom. t may concern.'

Be it known that I, MAURICE GALIBERT, a citizen of the United States,residing in the city, county and State of New York, have inventedcertain new and useful Improvements in Methods of Labeling Containers,of wlich the following is a specification.

This invention relates to a method cf paper' labeling containers havingan exteriorv shouldered surface; its object being to effect the labelingin such wise that paper or other temperable labels will be molded y intoconformity with the contour of the exterior wall. of such containers,and not be partially loose thereon presentinga partially wrinkled andaccordingly unsightly appearance, as is often the case in priorpractice. While my method is of particular utility in the mechanicallabeling of tubular containers having at each end an exterior flangedcap the inward edge of each flange forming an exterior peripheralshoulder or collar on the container, yet my method may be worked eithermechanically or manually on any shape of container having an exteriorshoulder which increases its cross-sectional dimension.

In the accompanying drawings forming a part hereof and illustrating theprinciple of this invention in the best mode now known to me of applyingthat principle,

Figure l is a lengthwise central section of an unlabeled tubularcontainer each end of which is provided with a cupped cap the flange ofwhich is exterior to the outward surface of the tubular body of thecontainer.

Fig. 2 shows the back' side of a paper label gummed in accordance withmy invention.

Fig. 3 shows the capped container of Fig.,1 labeled in accordancewiththis invention.

Referring to the drawings, 1 is a tubular container body, each end ofwhich is covered by a cupped cap 2, the flange 3 of which encircles thecontainer body and constitutes a peripheral shoulder or collar thereon,whereby the container surface to be labeled has relatively high and lowsurfaces.

The back of my new gurnmed or adhesively attachable paper label 4 isprovided either before or during the labeling operation, when there arevtwo exterior cap shoulders on-the container, with two opposed marginalgum strips 5, extending in the direction of the wrapping length of thelabel from end to end thereof, as shown. Inwardly of and adjacent eachsuch marginal gum strip 5, the label back is provided with an ungummedspace 6 parallel to a gum strip 5; and between the two gumless spaces 6,the label back is covered with an intermediate strip 7 0f gum of thefull wrapping length of the label. By strip, in this connection, ismeant a surface made adhesive applied moist as the label is beingapplied.

The point respecting the marginal strip or strips 5 is that the gum oradhesive is made liquid enough to temper the margin or margins of thelabels,-that is to soften and render them stretchable. The pointrespecting the intermediate gum strip 7 is preferably that the gum oradhesive shall be less liquid, that is of heavier body which will inpracticeV only negligibly temper the paper on which it is applied. Inactual practice, a thick adhesive is used for the gum strip 7, but it isnot intended to limit the invention to non-tempering of the papercorresponding to such strip because actual tempering of such portion ofthe paper might be successfully practised. The purpose of the twoparallel gumless spaces 6 is to afford clean, gumless surfaces on thelabel back for contact with mechanical labeling instrumentalities sothat the latter will not become gummed. The importanceof this is knownto all skilled in the labeling machine art. The width of each marginalgum strip or strips is approximately correspondent to the width of ashoulder or collar or flange of the container, thereby preferably tobeadhesively attached not only to the peripheralsurface of the collar,shoulder or flange, but also the inward edge thereof; and when thetempered and so stretchable margin or margins of the label are, appliedon the shoulder or shoulders, the label widthwise can be by suitablepressure molded to t the contour of the container, the intermediate moretenacious gum or adhesive on strip 7 holding the label to the body ofthe container while the stretchknown to me presents a much neater andmore desirable appearance, the more or less wrinkled appearance of suchlabels of such prior containers being eliminated. In such priorpractice, the labels have been smooth and tight around theshoulder-forming collars, or cap or cover iianges, and more or lessloose and wrinkled between them.

Containers labeled by the described labels and by the present method areeasily recognizable both by the smooth adhesion of the body of the labelbetween the end collars, and also, lin examination, by the presence ofthe gumless space or spaces 6; and by the relation of the gummed strip 7to one or more gumless spaces G and one or more gum strips 5.

So far as I now know, this invention finds its main and perhapsexclusive utility in the application of paper labels, but the inventionis susceptible of use in connection with any flexible label which has atemperable margin or margins. By gum is meant any suitable adhesive,whether of gum proper, paste, or otherwise. The word temper isextensively and commonly used in the paper label and paper working artsto indicate softening and consequent stretchability, and the elements,liquidity of the adhesive and time, enter into it.

The label or wrapper above described forms the subject-matter of myco-pending application Serial No. 261,224, and the labeled or wrappedcontainer above described forms the subject-matter of my 'co-pendingapplication Serial No. 261,223, both filed November 5, 1918.

1What I claim herein is:

1. The method of applying temperable labels to containers havingenlarged ends, which consists in making two applications of moistadhesive, one to marginal portions and the other to body portions of theseveral labels, to be applied along lines extending lengthwise of saidlabels such that at a definite time after said two applications havebeen made to a given label marginal portions of said given label will bemore highly tempered than the body portions thereof and at said timeapplying said label under pressure to one of said containers so that themore highly tempered portions of the label cover the enlarged portionsof the container.

2. The method of applying temperable labels to containers havingenlarged end portions, which consists in applying a slowly temperingmoist adhesive to the body portions of said labels and a more quicklytempering moist adhesive to marginal portions thereof. the applicationsbeing along lines parallel to one of the edges of each label andthereafter bringing said adhesives on a given label while still moistinto contact with one of said containers after the marginal portionshave become well tempered and before the body portions have becomesubstantially tempered, so that the more highly tempered portionscoincide with the enlarged end portions and subjecting said containerand label toa molding pressure.

3. The herein-described method of labeling with temperable labels acontainer surface having relativelyT high and low surfaces to belabeled, such method consisting in tempering with an adhesive, atemperable back margin of the label, and in applying to the label backspaced apart from the tempered margin a negligib-ly -temperingthickerbodied adhesive for attachment of the body of the label to thecontainer; and during the application of suchlabel, effecting astretching action of the tempered adhesive margin; and in molding thelabel under pressure adhesively to the opposed surface of the containerboth on its high and relatively lower surfaces.

4. The herein-described method of labeling with temperable labels acylindrical container surface having relatively high end j peripheralsurfaces and an intermediate pcf ripheral surface of lesser diameterthan the high end surfaces, all of which surfaces are to be labeled,said method consisting in tempering with an adhesive the temperableopposite back margins of the label, and in applying to the label backspaced apart Jfrom the tempered margins a negligible temperingthicker-bodied adhesive for attachment of the body of the label to thecontainer; and during the application of such label, effecting astretching action of the tempered adhesive margins; and in molding thelabel under pressure adhesively to the opposed surface of the containeron its high end suraces and intermediate relatively lower surace.

In testimony whereof I have hereunto set my hand this 31 day of October,1918.
